I don't understand how anyone can stand to even touch gacha mobile games. The predatory design puts me off any other appealing elements, and shows the publishers/devs to have so much contempt towards their userbase.

I played the SMT mobile game and it just got more and more slimy over time.
It constantly advertised its own sales, it was slowly harder to get anything worthwhile, leaving gameplay feeling stale, some summon ranks became locked behind pay-only...

I recently learned about the Dissidia gacha and the character interaction sounds really appealing to me, and supposedly the gacha is "fair", but also, nyeeeh. It's all ultimately trying to get you to throw money at chance.

And not throwing money at it still leaves things to chance, which is ultimately a time-waster.

A good game would make sure your work is earned in equal measure. A good game wouldn't decide that after hours of grind you failed simply because of random chance.
